CMT simplifies Vapor intrusion monitoring
Vapor intrusion refers to the movement of volatile chemicals from the subsurface into the indoor air of overlying buildings. The most common source is groundwater or soil contaminated with volatile organic compounds (VOCs). VOCs emit vapors that migrate into pore spaces of the soil and upward into the overlying environment. Generally, vapors enter buildings through cracks and openings in the ...

CMT for high resolution vapor intrusion monitoring
Background Vapor intrusion refers to the movement of volatile chemicals from the subsurface into the indoor air of overlying buildings. The most common source is groundwater or soil contaminated with volatile organic compounds (VOCs). VOCs emit vapors that migrate into pore spaces of the soil and upward into the overlying environment. Generally, vapors enter buildings through cracks and openings ...

NJDEP Finalizes the Vapor Intrusion Technical Guidance Document
Recently, the New Jersey Department of Environmental Protection (NJDEP) announced that they had finalized the Vapor Intrusion Technical Guidance document. The guide was designed to provide assistance in the evaluation of contaminated sites. According to the NJDEP, “The presence of volatile chemicals in contaminated soil or ground water offers the potential for chemical vapors to migrate ...

Vapor Intrusion Hazards and Resources to Protect Building Occupants
The New York State Department of Environmental Conservation describes vapor intrusion as the process by which volatile chemicals move from a subsurface source into the indoor air of an overlying or adjacent building. They share the fact that the subsurface source can either be contaminated groundwater or contaminated soil which releases vapors into the pore spaces in the soil. Vapors can also ...

Substance Gas Monitoring
Substance Gas Monitoring Substance gas monitoring – So, what can be done to mitigate the potential drastic effects? Whether a landowner, developer or regulator the objective is identical; to ensure that any existing or proposed development remains or takes place safely. But because of the temporal or seasonal effects on ground gas migration, monitoring has to be undertaken over a ...

ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations
Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of passive samplers enables them to be applied in large numbers, facilitating detailed mapping of contamination across a site, for the purpose ...

Triad expedites brownfields redevelopment in Fairbanks
The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...
